Detection of Apical Inflammatory Root Resorption Associated with Periapical Lesion Using Different Methods

Abstract

The aim of this study was to detect apical inflammatory root resorption (AIRR) associated with periapical lesion using cone beam computed tomography (CBCT) and scanning electronic microscopy (SEM). This clinical study evaluated AIRR in 88 root apexes, from 52 permanent teeth of 14 patients, extracted for different reasons. The patients were submitted to a clinical interview, review of dental/medical histories and clinical/imaging examinations for treatment planning. All selected teeth showed unrestorable condition because of the extensive coronal breakdown due to carious lesions, and root canal infection associated with periapical lesions. CBCT images were obtained from the patients with the aim of diagnosing the periapical diseases which showed complex or doubtful conditions. Two examiners assessed the presence or absence of AIRR. Apices were also analyzed under SEM. Chi-square test was used to compare the imaging methods for detection of AIRR. The level of statistical significance was set at 5%. AIRR associated with root canal infection and apical periodontitis was found in 61.4% of the cases studied by using SEM, and at least half of the cases by CBCT. The microscopic analysis remains as a reference standard against the imaging method to identify AIRR.

Prevalência de Lesões Periapicais Observadas em Radiografias Panorâmicas

“…A infecção do canal radicular após a necrose pulpar segue um percurso em sentindo apical, capaz de induzir a inflamação periapical, este processo pode levar a destruição dos tecidos periapicais e induzir a reabsorção e perda radicular. A perda dessas estruturas ocorre devido a atividades das células de defesa em eliminar os microrganismos que estão infectando a polpa, sendo assim a peripodontite periapical é a resposta imune do hospedeiro contra os microrganismos vindos do canal radicular (6).…”

Электронные апекслокаторы (ЭAЛ) являются одним из основных инструментов для определения РД в зубах.…”

“…Root canal infection follows a natural route in apical direction inducing infl ammation of periapical structures. 1 This infl ammation can stimulate the destruction of periapical tissues as well as loss of radicular tooth structure leading to apical root resorption. Conservative treatment goal in infl ammatory apical root resorption is to eradicate bacteria with non-surgical root canal therapy (NSRT) to allow healing of peri-radicular tissues thus arresting the resorption process.…”

Scanning Electron Microscopy Evaluation of Dental Root Resorption Associated With Granuloma

“…Some works have focused on the microstructural damage of the apical foramen and the restricted periforaminal area around it caused by the action of chronic apical periodontitis. Recently, other techniques have been introduced such as cone beam computed tomography, but for extracted teeth microscopic analysis remains a reference standard to identify apical inflammatory root resorption (Estrela et al, 2014).
